Description
Technical field
The utility model belongs to airtight detection field, and in particular to a kind of quick detachable Self-sealing valve.
Background technique
In airtight detection field, in order to which security needs detect internal gas density, need to install on test point
Self-sealing valve makes it also be to maintain sealing state when not detecting, and can make when needing to detect detect gauge outfit push into
Enter test point to be detected.Self-styled valve arrangement on the market is as shown in Figure 1, its disassembly is inconvenient now, and which results in lifes
Producer's high rejection rate is produced, a large amount of manpower and time are wasted in production, has aggravated the cost of enterprise.
Utility model content
To solve the above-mentioned problems, the utility model provides a kind of quick detachable Self-sealing valve, and structure is reliable, and leakproofness is good
It is good, and it is conducive to disassembly.
A kind of quick detachable Self-sealing valve comprising valve body, spool, the inner cavity of the valve body include the first cavity, the second chamber
Body, intermediate inner cavity and valve core channel, the diameter of the intermediate inner cavity is bigger than first cavity diameter, first cavity and institute
It states intermediate inner cavity to communicate, the intermediate inner cavity is connected with second cavity by the valve core channel；The spool includes the
A part and second part, the diameter of the first part is bigger than the diameter of the second part, the second part with it is described
Valve core channel forms clearance fit；First cavity is provided with circlip groove on the inner wall of opening, consolidates in the circlip groove
Surely there is retaining ring；The retaining ring is provided with washer towards internal direction, is provided between the washer and the spool first part
The spring of pretightning force.
Optionally, the spool second part outer wall is provided with core sealing groove, and the core sealing groove is fixed with sealing ring.
Optionally, the core sealing groove is opened in the junction of the first part and second part.
Optionally, the valve outer wall is provided with outer side seal groove, and the outer side seal groove is fixed with sealing ring.
After the utility model, when needing to detect, only needs are depressed spool with detection table, can make detection table
It is connect with inside, it is easy to detect；After detection terminates detection table movement, under the action of the spring, spool will automatically be sealed opening,
Guarantee the leakproofness of monitoring point.And find that product is problematic in process of production, it is only necessary to which the retaining ring that will be close to outlet removes, and pads
Circle, spring can pop up under the reaction force of initial tension of spring, and disassembly is more simple and convenient than existing mechanism, save for enterprise
A large amount of production cost.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the prior art；
Fig. 2 is the cross-sectional view of the utility model valve body；
Fig. 3 is the structure chart of the utility model spool；
Fig. 4 is the cross-sectional view of the utility model assembling.
Specific embodiment
A kind of quick detachable Self-sealing valve, including valve body 1 and spool 2.As shown in Fig. 2, the inner cavity of its valve body 1 includes first
Cavity 11, the second cavity 12 and intermediate inner cavity 13, the intermediate inner cavity 13 and second cavity 12 are connected by valve core channel 14
It connects, the diameter of the intermediate inner cavity 13 is bigger than the diameter of first cavity 11, inner wall of first cavity 11 close to opening
On be provided with circlip groove 15,1 outer wall of valve body is provided with outer side seal groove 16, and the outer side seal groove 16 is fixed with sealing ring；Such as
Shown in Fig. 3, the spool 2 includes first part 21 and second part 22, and the diameter of the first part 21 is than described second
Divide 22 diameter big, as shown in figure 4, the second part 22 and the valve core channel 14 form clearance fit；The circlip groove
Retaining ring 3 is provided in 15；The retaining ring 3 is provided with washer 4 towards internal direction, at first of the washer 4 and the spool
Divide between 21 and is provided with spring 5.The junction of the first part 21 and second part 22 offers core sealing groove 23, described
Sealing ring is fixed in core sealing groove 23.
The first cavity 11 is connected at test point the utility model when in use, when needing to detect, detects the gauge outfit of table
It is protruded into from the second cavity 12 and depresses spool 2, thus 1 the first cavity 11 of inside of valve body, the second cavity 12, intermediate inner cavity 13
It is communicated with valve core channel 14, detection table is just able to detect；Detection table is removed after detection, and under the action of spring 5, spool will
Self-return seals intermediate inner cavity 13 and 14 junction of valve core channel, guarantees the leakproofness of monitoring point.And in process of production
It was found that product is problematic, it is only necessary to remove retaining ring 3, washer 4 can pop up under the reaction force of 5 pretightning force of spring, and disassembly is more
It is simple and convenient, a large amount of production cost is saved for enterprise.
